The National Terrorism Advisory System (NTAS) replaces the color codes of the Homeland Security Advisory System (HSAS). The new alert system is currently in a 90 day implementation period that began on January 27, 2011 – until the end of the implementation period, the existing HSAS will remain in effect. NTAS will more effectively communicate information about terrorist threats by providing timely, detailed information to the public, government agencies, first responders, airports and other transportation hubs, and the private sector.
This page contains any current NTAS Alerts and archived copies of expired alerts.
Over the last decade, we have been made acutely aware of the possibility of major disasters caused by acts of terrorism. Terroristic threats and acts derive their power from confusion, uncertainty, and panic. Protect your family and your community through preparation. Know what to expect and how to respond in the event of an attack.
In times of emergency, local officials may instruct you to shelter-in-place. What does this mean?
This precaution is aimed to keep you and your family safe while remaining in your home. If you are told to shelter-in-place, take your children and pets indoors immediately. While gathering your family, you can provide a minimal amount of protection to your breathing by covering your mouth and nose with a damp cloth. Then take the following precautions:
Authorities may decide to evacuate an area for your protection. Again, it is important to stay calm, listen carefully and follow all instructions. If you are told to evacuate, listen to your radio to make sure the evacuation order applies to you and to understand if you are to evacuate immediately or if you have time to pack some essentials. Do not use your telephone. The telephone lines will be needed for emergency operations.
